Schrader cores alone should not be responsible for keeping refrigerant inside a system.  Caps with an 0- ring and a tab of Nylog have never done me wrong.

It's nice to not have to pull out the torches and N2 rig sometimes.  Bending where possible also cuts down on fittings.

Each time I've done them, the customer has been extremely happy with the comfort level of their home. 

I've been speaking to the guys that created AirMatch and I watched a video on some of the features. 

Their LaserCalc application allows for room by room load calculations based on ACCA manual J.

Yes, most know that the same mini split can be used across 10 different labels. 

But some labels can be better than others, even though the product is the same.  It starts with training, tech support and part support.  Whoever can do that the best will win.  Some wicked "tech centric" marketing doesn't hurt either.

I didn't have time to fully diagnose this at the end of the day but will be back later.

Initially the inlet pressure to this burner was high but then rectified.  The burner would not light off and then shut down on flame failure. 

When the manual shut off valve was throttled back to about 60% closed the burner lit and stayed lit, it also stayed lit when the shut off was opened back up 100%.

The manifold pressure on this, like on most high efficiency boilers is a neg...

Through my testing of this device, it has proven valuable.  When I installed mine 5 years ago, I put my contactor in a drawer just in case.  It's still there. 

The @copeland_company SureSwitch is a solid state contactor with sealed contacts, it provides additional compressor protection from brownouts. 

My favourite feature of the SureSwitch is that it is designed to prevent pitting and arcing through its control function.

This is a heat pump and should be up on a stand to keep it away from snow.  The piping is horrible and lazy.  This is what clients don't understand when they get a quote that seems too good to be true. 

Regardless of the install, the unit is cooling like a champ. 

This one had a leak at the flare nut.

Old school will tell you to run it for an hour...

But when you truly pay attention, time is not the indicator of a complete evacuation.  This 20 ton system was pulled down in 20 minutes by pulling the cores and using 3/4" hoses. 

This allowed me to use a battery powered vac pump and avoided running cords on a commercial roof. 

I used the @navac_inc NP6DLM pump and NH35AB 3/4" hoses and NVR2 core removal tool.

Keeping them alive...

Some relic R22 Carriers are getting resurrected for the summer and hopefully replaced next spring.

Someone put a screw on this condenser 😂. I've done it before but not this time.  You have to be very careful with the heat on these tubes as they are extremely thin.  Too much heat and you'll melt them. 

Also more testing of the @navac_inc Smart Probes.  The display right on the probe is definitely nice to have.

Two leak locations...

The first leak is on the body of the pressure switch, anything pressurized can leak, remember this. 

The second leak isn't actually on that coil, that corroded coil is hydronic.  The leak is buried in behind the hydronic coil on the reheat coil. 

What would your recommendation be here moving forward?

I am 46 years old and have been in the HVAC/R industry going on 29 years. Techs on FB that are my age with less experience than me, call me kid. 

I suppose I should stop learning and stop trying/testing new things so I can fit in.

A job well done...

On a winter visit to the town of Owen Sound Ontario I was pleasantly surprised to see that the contractor took the time to install not only surge protection but also voltage monitoring on this heat pump RTU. 

This is the RSH-50 VRM Kit from @rectorseal. 

Circuit boards have a large failure rate when the incoming power fluctuates too high or too low.  This kit will prevent unneeded failures and call backs.

Most that use a torque wrench for the first time are surprised by how much they've been over tightening a flare nut as per spec. 

I usually hit the mid range as per the manual torque spec and adjust if needed.

@burtshvac is using the @navac_inc torque wrench and a dab of @nylog @refrigerationtechnologies.

A service wrench was built for it...

First off, that's not a King valve, that's a suction service valve. 

To adjust the valve stem use a refrigeration service wrench, not an adjustable or channel locks.

In a pinch, a set of pliers wrenches will work as they're flat, lock in place and don't slip. 

@ritchieyellowjacket has been manufacturing service wrenches for decades.

A thermistor is a resistor that changes resistance due to a change in temperature.  In the video we are using an NTC (negative temperature coefficient). This means the resistance will drop on a rise in temperature.  PTC (positive temperature coefficient) has a rise in resistan...

I had to replace a bearing on this Daikin air handler providing make up air to high rise hallways and then perform a start up.  I also had a fan balancer come in and balance the blower wheel. 

The make up air had no ducted return and the return static was almost 0" wc.  The supply static was 2.4" wc at 60Hz.
This pressure is well within the specs of the system.  I used the @testonorthamerica 510 dual port manometer to check this.

Midea RAC designed this Window Package Heat Pump for high rise buildings in New York City.

Word on the street is tenant spaces in some areas will have a max temp they can be at, just like they have a min temp they must maintain.  Essentially, some rented spaces will be forced to provide air conditioning if they don't already. 

I think the atmomized condensate is a cool feature.

There's a few manufacturers that do this, York also but it's a one piece harness.  From time to time, I see the terminal box melted from moisture penetration. 

What has really helped is silicone grease, it prevents moisture from getting inside the connection.

I'm using @refrigerationtechnologies silicone grease on this Lennox unit.  It's dielectric and won't pass current.

The suction pressure at random times will drop off to 90 psi while the high side remains stable.  Then magically it runs stable again after a few minutes.

It also, out of nowhere, went off on high pressure after it ran for about an hour, just a quick spike and off.
